Meet the people behind Rella

Leadership

Dr. Zachary Wagner

DO · Founder & Owner

Medical Weight-Loss Physician

An American Board of Obesity Medicine diplomate, Dr. Wagner leads Rella's medical weight-loss care. He works directly with patients to understand their history, goals, previous efforts, and safety considerations before recommending a next step.

He founded Rella around a simple idea: people should feel heard before they are asked to make a decision. His approach is clear and individualized—explain the options plainly, recommend only what makes sense, and build a plan that can be supported over time. Dr. Wagner does not perform aesthetic treatments or injections; those services are provided by Rella's aesthetics team.
